But the author gives example of reselling iPods. I'm not aware of discounted wholesale pricing on iPods, so how would you make a profit without ripping people off (i.e. selling over Apple's price)?
There is wholesale pricing on Apple devices. How else could a store make money on them? Stores don't buy stock directly from Apple; they buy through an authorized distributor.
P.S. In case it wasn't clear to you, Apple devices cost the same from anywhere. That makes them a good example here.
